Lighting | Imaging | Telecom p Thermopile Infrared Detectors Dual Channel Thermopile TPS 2534 Thermistor temperature reference included Applications: infrared absorption (NDIR) gas sensing with reference channel The dual thermopile sensor TPS 2534 employs two single thermopile chips mounted in a TO 5-type housing with a 30 kV thermistor as temperature reference. The cap has two windows of size 2.3 x 2.6 mm2 each which can be equipped with different infrared bandpass filters. The sensor is perfectly suited to gas detection by IR absorption.
